Effects of Trichoderma reesei Additive on the Nutritional Value of Feed Produced by Distillers Grains

Distillers grains is the by-product in liquor-making and could be used to produce feed through solid-state fermentation. In this study, the effects of adding different levels of Trichoderma reesei on the nutritional value of feed produced by distillers grains were investigated by comparing crude protein, crude fat, total sugar, crude fiber, and amino acid compositions before and after fermentation. The results suggested that, the addition of 5 % Trichoderma reesei could achieve the highest nutritional value after solid-state fermentation.
